Quick Links
Lenses are incredibly powerful items inLast Epochthat allow you to target farm almost anything in the game. The ability to target farm specific loot eliminates RNG to some extent. However, this does require a lot more grind compared to Merchant’s Guild, where you can purchase your desired items at the marketplace.
To use Lenses, you must be a part of the Circle of Fortune in The Observatory. You reach this area near the end of the campaign, so you will need to progress a bit before you can experiment with it.

Last Epoch Prophecies Explained
Lenses are exclusive toCircle of Fortune, one of the two factions in Last Epoch. You can think of Circle of Fortuneas the Solo Self-Found mode inPath of Exile. There is no trading with other players, and you must farm everything yourself. In order to join Circle of Fortune, you must reach the ninth chapter during the campaign andspeak with Galila in The Observatory.
The other faction,Merchant’s Guild,is perfect for players who prefer to tradefor their desired items.

After you have joined the Circle of Fortune, you will seefour Telescopes in the area. These are:
Interacting with these Telescopes willshow you a few Prophecies that you can purchase byspending Favor. Each of these Prophecies will have a specific condition, such as defeating Chronomancer Julra inThe Temporal Sanctum dungeon, and will reward targeted loot i.e. Unique Bows, Small Idols, Set Items, etc.

If you cannot find a Prophecy that you want,you also have the option to reroll available Prophecies for a small amount of Favor, displayed in the bottom-middle of the screen.
But what if you want to target farm something that does not appear in any of the Prophecies? This is where Lenses come into play.

How To Get Lenses
To purchase Lenses,speak with Galila at The Observatory. Lenses cost Favor, which is a currency that you can earn by doing about anything in the game while being a part of COF. Aside from Favor, some Lenses also require you to be at a specific rank with the faction. Lenses are divided into two categories:Regional LensesandGreater Lenses.
Regional Lenses are specific to one type of item, like Arms, Two-Handed Swords, etc. and can only be applied to the appropriate Telescope. For instance, an Arctus Lens can only be slotted into the Arctus Telescope.Greater Lenses, on the other hand,can be slotted into any Telescope.

Please note thatLenses are permanent items. Once you have used them, you can store them in your Stash.
How To Use Lenses
